Sizing Guidelines

This section is intended for professionals who search for a best practice answer to sizing-related issues, and assumes you have already read the whole Veeam Backup for OLVM and RHV User Guide.

Be aware that a best practice is not the only answer available. It will fit in the majority of cases but can also be totally wrong under different circumstances. Make sure you understand the implications of the recommended practices, or request assistance. If in doubt, reach out to Veeam professionals on Veeam R&D Forums.

Backup Appliance

While allocating compute resources to the backup appliance, consider the following recommendations:

Number of VMs in Cluster

Number of Jobs

Resources for Management Tasks

Resources for Embedded Worker

< 1000

< 100

No additional resources for management tasks

1 vCPU and 1 GB RAM for each concurrent task

> 1000


1 vCPU, 1 GB RAM

It is not recommended to use the embedded worker for large deployments. Disable the embedded worker and use dedicated workers instead.

> 5000

> 300

2 vCPU, 2 GB RAM



To modify the backup appliance settings, use the Veeam Backup & Replication console as described in section Editing Backup Appliance. Allocating resources to the VM running as the backup appliance in the oVirt Administration Portal may cause technical issues.
